摘　　要：采用 N72 0 7从无机酸体系中萃取钼 ,考察了影响萃取平衡的主要因素 ,筛选出反萃取条件。萃取钼的最佳条件为起始水相 p H值为 2 .3,萃取剂浓度为 0 .0 1m ol/L ,经二级错流萃取 ,萃取率可达 99.40 % ,而采用 0 .5 mol/L的氢氧化钠反萃负载有机相 ,一级反萃率可达 10 0 % ,并经紫外可见光谱确证 。This thesis report that N 7207 extract Mo(VI) from mineral acid body system,and study the main factors that affect the extraction balance,and select the inverse extraction condition.The best condition of N 7207 extracting Mo(VI) is that the pH of beginning water is 2 3,and the density of the extractant is 0 01 mol/L.By Secondary extraction,the efficiency of extraction is 99 40%.The inverse efficiency of extraction is 100% by NaOH of 0 5 mol/L.By ultraviolet and visible spectrum,the mechanism that N 7207 extracts Mo(VI) is anion displacement reaction that attribute to ion association object extraction body system is discussed.
